Abstract

This project aims to build and test micromechanical-based frequency synthesizer
components that meet or exceed the requirements of the GSM standard. Towards these goals, the
project investigates short and long-term stability of MEMS-based oscillators, particularly, phase
noise and acceleration sensitivity. In addition to providing a highly accurate, on-chip frequency
reference, a fully-integrated oscillator can achieve greater stability (particularly acceleration
sensitivity) and far less power consumption than any comparable off-chip oscillator. In the
process of achieving a fully-integrated frequency synthesizer, much of the research is expected
to focus on development of integrated resonators-ASIC oscillators, as well as other needed
components such as MEMS-based frequency dividers.
